The anime premiered from July 12th 2013 to September 27th 2013.An OVA was released with Volume 7 including the 'True Ending' of the series.[1]

Hyperdimension Neptunia: The Animation appears to take place in Gamindustri. Each nation (Lastation, Leanbox, Lowee, and Planeptune) also makes an appearance, from each nations' inner cities to dungeons and pastures within their vicinities.

In Planeptune, the CPUs of Gamindustri have signed a friendship treaty, banning the use of military force to take Shares. A month has passed since then. With the Planeptune's Shares declining shown through the power of the Sharicite due to idleness, Neptune decided to learn more about the duties of a CPU from Noire. Noire initially declined to help, but she later helps Neptune by getting her assigned to a monster extermination mission. Neptune, with the help of Nepgear, IF, and Compa, took care of the Dogoos in Nasuume Highlands, while Noire took care of the monsters in Toruune Cave. In HDD form, Noire handled the monsters within with ease until she reverted back to her human form for an unknown reason. Cornered by an Ancient Dragon, Noire was overwhelmed until Neptune went and defeated the Ancient Dragon. Somewhere near Toruune Cave, Pirachu and Arfoire was revealed to be searching something within the cave. Planeptune gained some Shares, but it's unknown whether it's due to Neptune completing the mission or certain photos of Nepgear that were leaked on the Internet.

On Lowee, Blanc overexerts herself with work, while her sisters Rom and Ram are pulling pranks much to her annoyance. Neptune, Nepgear, Vert, Noire, and Uni make a visit to Lowee and take Rom and Ram to an amusement park, while Blanc stays behind to continue working. Rom and Ram are kidnapped by CFW Trick and Linda. Blanc becomes exhausted after Abnes shows up to interview her after leaking out the kidnapping to the public. With the help of Vert and Leanbox's advanced technology, Rom and Ram are located. Trick abuses the girls by licking them repeatedly, while Linda plots a ransom for the girls. But their plan was foiled when Neptune, Noire, and Vert arrive and use their HDD powers. Rom and Ram are saved when Blanc arrives and defeats Trick with her powers as White Heart. Blanc then apologizes to Rom and Ram for being too hard on them. Meanwhile, the maid that had been serving Blanc is revealed to be Arfoire in disguise, and she is in possession of red crystal.

Vert invites the other CPUs and their sisters to Leanbox for a party. They go to a 5pb concert, with the exception of Vert, who the girls later find out is too busy playing a MMO and did not prepare for a party. Disappointed there was no party, the others decide to prepare it themselves instead. On the way back from shopping for party food, Nepgear picks up a red crystal dropped by a mouse and suddenly becomes dizzy, while the mouse runs away with the crystal. During the party, a mass monster outbreak occurs on a nearby island and the CPUs go to stop it before it reaches the town. Meanwhile, IF finds out the mouse is on the blacklist for every country and took a boat to the same place where the outbreak was. Finding that suspicious, IF and Nepgear head out to the area. After defeating the monsters, the CPUs are captured by Arfoire in a barrier made by the Anticrystals, slowly draining their Share power. IF and Nepgear arrive too late, only to be shocked by the sight of the captured CPUs.

When the CPU's get captured, Nepgear tries to go save them, but IF stops her and they ride back to Leanbox. When they learn about the anticrystal, Nepgear says that it's her fault they don't have it because she saw one of the anticrystals in Episode 3 when Pirachu dropped it, but she didn't know what it was. Uni calls Nepgear an idiot because her sister, Noire, got captured by Arfoire and runs off. Meanwhile, Neptune was complaining about how she was not able to play games and Vert, who had an appointment with her guild, wished she had the Four Goddesses Online chat room. Neptune decided to tell Arfoire she wanted to play some games while getting her name wrong. An annoyed Arfoire tells the Goddesses to enjoy what little time they have left. Uni apologizes to Nepgear about calling her an idiot and then the four sisters decide to become stronger in order to rescue their older sisters.

Nepgear's transformation help gain the upper hand for a while until Arfoire use her own transformation. The other three candidates then discover their own transformation and fight together with Nepgear. In the middle of battle the four Goddesses are swallowed inside the anti-crystal field, causing the candidates to lose hope and turn the tide of battle once again. Just when all hope is lost, Nepgear realize the Goddesses are still fighting for their survival inside the now blacken crystal field, she gather her resolve alongside Uni, Rom and Ram and proceed to defeat Arfoire in a team attack. The end shows the four Goddesses reunite with the candidates and Pirachu carrying a wounded Arfoire away. Also, Peashy makes her appearance at the end.

Lastation's security was compromised when an anonymous hacker hacked into their satellite. As the four Goddesses gather to discuss how to catch the hacker, Uni consults Nepgear over Noire's recent behavior of locking herself in her room. Nepgear suggests placing a hidden camera inside Noire's room to discover what she's been doing, but instead found other hidden cameras already placed there. The four Goddesses track the hacker's location down with the help of a female Bi** Gates, with the candidates also going to the same location by tracing the hidden cameras. The Goddesses confront the hacker, a flamboyant man name Anonydeath, who turn out to be a huge fan of Noire. Anonydeath has been taking pictures of Noire using the hidden cameras in her room, which show her cosplaying various characters. Noire attacks Anonydeath in rage but Anonydeath manages to slip away, only to run into the candidates. Anonydeath gave himself up leaving an embarrassed Noire trying to tell the candidates to forget everything they saw. Back on Lastation's Basilicom, Noire discuss her cosplay hobby with Uni, only to be hit by a girl fallen from the sky. The girl introduces herself as Plutia, the Goddess of Planeptune, much to everyone's surprise.

Plutia is revealed to be the Goddess of Planeptune from another dimension. A smaller version of Histoire explains Plutia was sent to recover something that was causing energy from Plutia's dimension to flow into Neptune's dimension. As Plutia, Neptune, Nepgear and Peashy get acquainted, IF and Compa were kidnapped by Arfoire and Pirachu. Neptune, Nepgear and Plutia arrive at an eggplant farm in an attempt to rescue them, but Neptune's hate for eggplant causes her transformation to break, leaving Nepgear alone to fight a horde of eggplant monsters. While IF was getting suggestively tortured by Arfoire, Plutia snaps and transform into a very sadistic Goddess, defeating both Arfoire and Pirachu. Defeated and having spent all her money on the eggplant farm, Arfoire decides to give up world domination and becomes an eggplant farmer, with Pirachu helping her.

The Forbidden Paradise (Island)

August 30, 2013 JP

Lowee's satellites discovers an artillery battery on the R-18 Island, and the more mature looking Goddesses head out to investigate. At the R-18 island, Neptune, Noire, Vert and Nepgear pass through the security checkpoint in their Goddess form with ease, while Blanc in her Goddess form had to destroy the checkpoint to gain access because it was repeatedly asking Blanc and Plutia in her human form for confirmation of their age due to their small breast size. The Goddesses then decide to take a detour for some naked antics at the beach. When they proceed to the artillery battery, they found the battery appear to be nothing more than a bubble making machine. The Goddesses return to Planeptune, only to find out Peashy returned to her mother, leaving Neptune depressed.

Neptune tries to not think about Peashy by overworking herself. This gets Plutia angry, and she fights Neptune. Just when Neptune finally becomes honest with herself, they were informed a new nation, Eden, was formed on the R-18 Island. The Goddesses go and find Anonydeath, who reveals the Anonydeath in Lastation's prison was only his body double. Noire tried to attack Anonydeath, only to be intercepted by the Goddess Yellow Heart. Yellow Heart proceeds to fight all the Goddesses, while appearing to take no damage herself. Neptune, Noire, Vert and Blanc finally surround Yellow Heart and unleash a barrage of attacks on her, causing her transformation to break. Yellow Heart turns out to be Peashy, to the shock of the Goddesses. Anonydeath and his accomplice Rei Ryghts then declare Peashy as the Goddess of Eden and demand permission that either all the 18+ goods made in Eden to be exported to other nations in unlimited quantities or they would declare war.

Peashy leads Eden's soldiers to invade Planeptune, while IF and Nepgear lead Planeptune soldiers to intercept. Meanwhile riots break out in Lastation, Leanbox and Lowee, preventing the other Goddesses from helping Planeptune. Neptune loses the will to fight but is encouraged by Noire and Plutia, which made her gather her resolve to confront Peashy. Neptune use a pacifist approach to attack Peashy's memory, while Plutia and Noire, leaving Lastation to Uni, infiltrates Eden. Plutia and Noire successfully destroy Eden's source of power, causing the riot to calm, and Eden's soldiers regain their senses. Peashy reverts back to her human form. Having found Peashy as the one she was looking for, Plutia takes Peashy back to their world, with Peashy finally regaining her memory just as they teleport.

Planeptune's share had skyrocketed due to stopping Eden's invasion. Neptune planned to hold a festival to celebrate the occasion. However, Planeptune's rise in shares has caused the other three nation's shares to drop, which made Noire, Vert and Blanc to decline invitation to the festival. Neptune was call to a forest by Blanc, where Blanc suddenly attacks Neptune, accusing Planeptune to have stolen her new shares. The attack was stopped by Rom and Ram, but Blanc threatens war. Neptune returns to Planeptune, only to find Rei Ryghts transformed into a Goddess and destroyed part of Planeptune to recreate the ancient nation of Tari. Rei destroys Planeptune's Basilicom in a show of power, also crippling Planeptune's communication in the process, preventing any call for help.

Neptune is overwhelmed by Rei's power until reinforcements from the other 3 nations arrive. Rei reveals that her goal was not to rule the world but to simply destroy it. The eight Goddesses worked together to destroy Tari and her super weapon. Rei is unfazed by the destruction and plan to self-destruct as another mean to destroy the world. The eight Goddesses surround Rei and join all their share energy together, ready to sacrifice themselves to stop the destruction. A tremendous blast occurs, but the Goddesses were able to contain it. The eight Goddesses survived, but were all reverted back to their human forms. Rei Ryghts also survived, and planned to use her remaining energy to at least kill the eight Goddesses. Just as Rei was ready to kill the Goddesses, Arfoire arrive and uses the Anticrystals on Tari's share crystal, sealing Rei's power and saving the Goddesses. Several months later, at a ceremony to celebrate the completion of the new Planeptune Basilicom, Neptune announces the dissolve of the friendship treaty, stating they no longer need it because the Goddesses were now true comrades.

The little sisters are infected with the Bad End Syndrome, which causes them to have nightmares. In order to cure it, Neptune and Vert travel to Plutia's dimension to obtain the Shimmering Flowers. At their destination, Neptune is reunited with Plutia and Peashy, and meets the other dimension's Noire, Vert and Blanc. With the aid of the alternate CPUs, Neptune and Vert ascend a 10000-floor tower which has the Shimmering Flowers at the top. Neptune ultimately obtains the flowers, but when Peashy is in trouble fighting a monster, Neptune sends Vert back with the flowers and goes to help Peashy, despite being unable to use her Goddess transformation in this dimension. Only Vert makes it back to the dimensional gate in time, while Neptune misses the gate and is stuck in Plutia's dimension. However, on the way out of the tower, Neptune accidentally opens another gate between the dimensions, permitting unlimited travel between the two. With the 2 worlds linked, the Goddesses all meet and befriend their counterparts, and Neptune celebrate the occasion with a toast of pudding.

Episode 13 has a different opening animation sequence, this mainly involves characters from both Hyperdimension Neptunia Victory and the normal cast. Most shots of the opening are from the previous episodes.
